Your solution worked!
When LB loaded the old prefs the device showed up as a 644xg.
Looked at the scanning offset.
Took a picture.
Reverted back to the new prefs.
Laser shows as a 320A.
Entered in the previous values.
All good to go now.
When updating LB or as a backup procedure would it be possible to have LB automatically save individual settings (scanning offset adjustment, camera configuration, etc. Anything that can be saved as an individual configuration) to one file? Or is prefs a “global” save of all these individual settings?
It would be nice to have a file like that so you could send all the configurations to another computer for one that designs on several computers.
